Abstract: A prediction unit predicts a limit time at which a limit request value corresponding to a minimum acceleration or torque is reached when a vehicle is decelerated with only a first deceleration control by a drive device based on change over time of a request value indicating a degree of longitudinal direction vehicle acceleration. A mode determination unit selects one of: a first mode in which only the first control is executed, and before the limit time is reached, in addition to the first control, a second deceleration control is started by a braking device; or a second mode in which only the first control is executed, and before the limit time is reached, in addition to the first control, a braking preparation control is started. A calculation unit calculates an operation amount of the drive and braking devices based on the request value in accordance with the determined mode.

Abstract: A vehicle control device is configured such that if, during an automatic driving mode in which a vehicle is automatically driven regardless of operations by a driver, such automatic driving mode is temporarily stopped by a prescribed operation by the driver and a normal driving mode in which the vehicle is driven in accordance with the operations of the driver is entered, and thereafter the automatic driving mode is returned to from the normal driving mode, specific control is implemented in the post-return automatic driving mode, such control being determined on the basis of the driving state of the vehicle during the normal driving mode before the return.

Abstract: A control device is applied to a vehicle that has a braking device configured to be able to adjust the braking force applied to the vehicle. The control device has a stopping braking force imparting unit that controls the braking device in order to apply a stopping braking force to the vehicle, as a minimum value of the braking force required to keep the vehicle stopped. The control device also has a deviation quantity deriving unit that derives a deviation quantity between a state quantity of the vehicle obtained when the stopping braking force is applied to the vehicle by the stopping braking force imparting unit and an ideal value of the state quantity of the vehicle. The control device also has a stopping braking force updating unit that updates the stopping braking force on the basis of the deviation quantity derived by the deviation quantity deriving unit.

Abstract: A collision avoidance ECU sets a model deceleration change amount to smaller value in a state in which it is difficult to reduce the speed of a host vehicle than in a state in which it is easy to reduce the speed of the host vehicle. The collision avoidance ECU calculates a first target value by multiplying the model deceleration change amount by the elapsed time. The collision avoidance ECU obtains a subtraction value by subtracting the current reference relative deceleration from the first target value. Then, the collision avoidance ECU determines a target relative deceleration to be a greater value when the subtraction value is large than when the subtraction value is small, and carries out brake control so that the reference relative deceleration approaches the target relative deceleration.

Abstract translation: 防碰撞ECU在难以降低本车辆的速度的状态下比在容易降低主车辆的速度的状态下将模型减速度变化量设定为较小的值。 碰撞避免ECU通过将模型减速度变化量乘以经过时间来计算第一目标值。 碰撞避免ECU通过从第一目标值减去当前基准相对减速度来获得减法值。 然后，当减法值大于减法值小时，碰撞避免ECU将目标相对减速度确定为更大的值，并执行制动控制，使得基准相对减速度接近目标相对减速度。
